The most advanced and tanky tank available, the Sphinx is built to destroy all Armored Vehicles that come in its warpath. It fires anti-Special armor shells and features Composite Armor, resilient against most forms of damage, especially higher amounts. It also comes equipped with counter-air weaponry to give it a chance to strike down aerial threats like Saints and Black Queens.
The Sphinx fires anti-special armor shells that are extremely effective against Tier-3 units and overall decimates all air units with its air cannon. It is very dangerous to see on the field and must be destroyed immediately.
Its main cannon will decimate Special Armor if you let it get close, easily tanking it as if it was nothing with the support of Meditecs. This makes it particularly effective against Hover Tank platoons and android soldiers with Special armor, like the A27-Pride and A28-Gladiator.
"What Air units?" the Sphinx will say as it decimates all air that come before it, with its high range and damage, not much will stay in the air long with this unit around.
Sphinxes have the highest health of any unit in the game, only second the to base. With enough healing backing them, a single Sphinx can eternally hold back many late-game assaults with ease and stall for easy Influence and resource acquisition.
Although effective against ground and air, it moves very slowly and its ground weapon fires like a sniper. This gives the enemy ample time to prepare low cost infantry to distract its fire from the important units.
The main cannon may be very effective against Special, but it does not do a good job at having the range necessary to do so. It will be a hard time pushing this unit to where it needs to be without being countered by its main opposition.
Despite all of its strengths, this unit will melt to infantry units. S-Marines, A25-Romans and A26-Legionnaires are the main counter to this unit and will shred it if left exposed and undefended. Meditecs will not be able to heal the incoming damage by themselves.
80 Influence is a high cost for a single, albeit powerful, unit. Sphinxes are only likely to appear deep into late-game when Tier 3 threats are common and plentiful, and although they work fairly well in this environment, working to them is an investment that must be planned.
Constructing this unit will immediately provide you with much needed space, by scaring off air threats and forcing back Tier-3 units that may have taken up post near your base. You can use this time to build up a counter-offensive against the enemy forces.
This unit with its health and armor will absorb incoming missiles and defend units behind it from danger. With meditecs, this will render missiles useless.
If your enemy has a lot of air, this unit is what you will need to put a stop to it. Bring this unit out to force the battle to the ground!
